Definitions

  • the invention relates to a device for separating a parts mixture, in which a sieve bottom is displaceable by means of a crank mechanism in a running in a vertical longitudinal plane rotational movement.
  • the invention has for its object a device of the type mentioned above to modify so that a reliable separation while avoiding penetration of good to be separated between fixed and moving parts.
  • this object is achieved in that the sieve bottom is provided on the longitudinal side in view of known manner with upstanding side walls, and that the sieve bottom is arranged horizontally or approximately horizontally, wherein the crank drive engages the side walls.
  • the crank mechanism can be formed by eccentrics mounted in the side walls, whereby the arrangement on the underside is free of facilities obstructing the discharge of the sorted material.
  • the sieve plate can be divided into individual gradual adjustable and fixable step-like sieve elements which are attached to the continuous side walls.
  • the fixable screen elements with the end walls facing away from the associated end walls pivotally mounted on the side walls and the end walls bearing end edges in circular arc-shaped elongated holes can be performed adjustable.
  • the individual stage sections are adjustable in different inclinations over the longitudinal course of the entire device.
  • the end walls of the sieve elements can project beyond the sieve bottom elements, which has the advantage that the sieved material underneath the sieve bottom is evenly distributed in the receptacle by the movement.
  • Fig. 1 shows diagrammatically a first simple embodiment
  • Fig. 2 shows a variant with adjustable sieve plates in side view with removed front side wall.
  • the side walls of the device are referred to, on which an existing sieve elements 3 sieve plate is attached.
  • eccentric drive means 6 are mounted, which put the screen bottom in rotation in rotation during rotation.
  • the sieve bottom is designed step-like, wherein each of the steps has an end wall 5 which closes off the interspace between the individual sieve bottom elements 3.
  • the sieve bottom or its elements is fixedly arranged with respect to the side walls, wherein the overall arrangement is mounted substantially horizontally on a support frame, not shown, on which also the drive for the eccentric 6 is provided.
  • the end walls 5 project downwardly with respect to the sieve bottom, whereby distribution of the material passing through the sieve below the separating device is achieved.
  • the operation of the device is such that the material to be separated 1 is thrown from above onto the sieve elements 3 and receives by the rotational movement of the device a shock having both a vertical and a horizontal force component. While the vertical component of force causes the parts of the material to be separated to be repeatedly thrown up, the horizontal force component causes horizontal movement of the parts of the material to be separated, which either move depending on the body shape and rigidity of the parts of the material to be separated in one or the other direction causes.
  • the sieve elements 3 and the attached end walls 5 may have the same perforation or mesh size, or it may be the end wall 5 made tight, which means no change for the function.
  • the rotational movement of the tub is between 100 and 250 revolutions per minute, with an amplitude of 40 to 140 mm is provided.
  • the adjustment of the parameters takes place in each case depending on the nature of the material to be separated.
  • the screen elements 3 are arranged adjustable with respect to the horizontal, with one end edge are rotatably supported on the side walls 2 and with the other end edge, which has the end wall 5, they are along one in 4 indicated arcuately curved elongated hole, so as to be able to adjust the inclination of the screen element 3 with respect to the horizontal.
  • the radius of curvature of the elongated hole 4 corresponds to the width of the sieve element 3 measured in the longitudinal direction of the device.
  • the end walls 5 are dimensioned so that the bottom edge of the end walls is approximately in the region of the bearing of the next sieve element 3 when the sieve elements 3 are in the strongest position. The further the employment of the sieve elements 3 with respect to the horizontal is reduced, the more the lower edge of the end wall 5 projects downward, whereby, as already indicated, the downwardly protruding region of the end walls serves to distribute material fallen through the sieve evenly.
